How is a good thing to scream into every shot in a rally, constantly boo you're favourite's opponent, or yell stuff like "go home Denmark"? Badminton is played in small indoor arenas, where this stuff is actually very distracting. It is nothing but intentionally trying to unsettle players who've worked every day for years to be in a position to compete for those tournaments. That people actually go to tournaments and think they're entitled to influence games with this behaviour is a sign of pathetic character. You can support your own players and your own team without being a disrespectful xxx to the opponent. And to top that off, when a player actually reacts and show "ears", they whine about it. If you can dish it out all game, at least be able to take it for a few moments afterwards. Whiny b......, the lot of them.
